Latest Message<\/th>\nTitle: Some attendees may receive an unexpected cancellation message when an Exchange Online shared calendar event is updated<\/p>\n

User impact: Attendees may receive an unexpected cancellation message when an Exchange Online shared calendar event is updated.<\/p>\n

More info: Impact is intermittent and specific to calendar event updates that are made on behalf of the organizer using classic Outlook desktop client with the calendar sharing improvements enabled.<\/p>\n

Current status: We’ve completed enabling the change across the impacted environment and are monitoring to validate service stability.<\/p>\n

Scope of impact: Some attendees with enabled calendar sharing improvements may be intermittently receiving cancellation messages for updated shared calendar events when the event is still active.<\/p>\n

Start time: Thursday, June 5, 2025, at 12:00 AM UTC<\/p>\n

Estimated time to resolve: We anticipate the changes for our secondary fix will be enabled by Thursday, August 28, 2025, at 6:00 PM UTC.<\/p>\n

Root cause: Impact occurs due to a code issue triggered when meeting organizers are added as a required meeting attendee.<\/p>\n

Next update by: Friday, August 29, 2025, at 10:00 AM UTC<\/td>\n<\/tr>\n
